  - Returns detailed error with all occurrences when multiple matches found in strict mode
  - Particularly useful for AI-powered code review tools that analyze diffs
- Created comprehensive line matching algorithm that:
  - Parses diffs to find exact code snippets

### Changed
- Updated comment fetching logic to handle Bitbucket Server's nested comment structure
  - Server uses `comments` array inside each comment object for replies
  - Cloud continues to use `parent` field for reply relationships

    - Pagination support with `start_line` and `line_count` parameters
    - Tail functionality using negative `start_line` values (e.g., -50 for last 50 lines)
    - Automatic truncation for files >50KB to prevent token overload
